[0045] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0046] Figure 1 This is a schematic diagram of a power adapter board disclosed according to an embodiment of the present disclosure. This embodiment can be applied to providing power to multiple image processors.

[0047] The power adapter board 100 includes a power connector 101, a signal connector 102, an image processing connector 103, and a power type adapter module 104. The signal connector 102 is connected to the power type adapter module 104, the power connector 101 is connected to the power type adapter module 104, and the power type adapter module 104 is connected to the image processing connector 103.

[0048] The power connector 101 may refer to the power supply circuit on the power adapter board 100. The power connector 101 is used to connect to a power supply module and transmit power to components that require power through the power adapter board 100. The power connector 101 includes multiple ports and can connect to multiple power supply units (PSUs).

[0049] Image processing connector 103 may refer to the circuitry on power adapter board 100 that connects to the GPU. Image processing connector 103 is used to connect to an image processor and, through power adapter board 100, receives power and supplies it to the connected image processor. Image processing connector 103 includes multiple ports and can connect to multiple image processors (GPUs).

[0050] Signal connector 102 may refer to a line on the power adapter board 100 that transmits data signals. Signal connector 102 is used to connect to the mainboard, specifically the controller on the mainboard. Signal connector 102 is used to connect the power supply module and the image processor, establishing a connection between the controller and the power supply module, and between the controller and the image processor.

[0051] Power type adapter module 104 is connected to power connector 101 and image processing connector 103. Power type adapter module 104 is used to process the power current transmitted between power connector 101 and image processing connector 103 to ensure compatibility with different types of power supply modules used by the image processor. Specifically, power type adapter module 104 can limit power supply based on voltage and / or current, thereby improving power supply security.

[0052] Accordingly, power connector 101 is used to input the power current provided by the power supply module to power type adapter module 104; power type adapter module 104 is used to input the received power current to image processing connector 103, so that image processing connector 103 can provide it to the image processor. Signal connector 102 is also used to receive type information of power supply module 104 and forward it to the controller, as well as receive adaptation control signals sent by the controller and forward them to power type adapter module 104 to adapt the power type adapter module 104 to the type of power supply module.

[0053] The type information describes the type of power supply module 104 and may include at least one of the following: the model of the power supply module, the adapted capacitor, the provided power voltage, and the adapted power current. The adaptation control signal controls the power type adaptation module 104 to adapt to the type of power supply module. The adaptation control signal may be a signal that controls the power type adaptation module 104 to process the transmitted power current. Specifically, it controls the power type adaptation module 104 to process the power current provided to the image processor into the power current adapted to the power supply module.

[0054] According to the technical solution disclosed in the present invention, an independent power adapter board is used to power the GPU, which can not only meet the power supply requirements of high-power GPUs, but also be independent of the motherboard, realize power decoupling, expand power consumption, reduce the space occupied by the motherboard, adapt to GPUs with higher power consumption, and do not need to modify the motherboard, thereby reducing the implementation cost of power supply. At the same time, it avoids the GPU and the motherboard from sharing power supply, and improves the stability of the power supply system. Through the power type adapter module on the power adapter board, it can be compatible with different types of power supplies, improve the compatibility of the power adapter board, and provide adaptive power current for GPUs with different power consumption requirements, thereby improving the expansion capability of the motherboard.

[0055] Optionally, the power type adaptation module 104 is a power current limiting module, which is used to receive an adaptation control signal and control the output power current to be less than or equal to a current corresponding to the adaptation control signal.

[0056] The power current limiting module is used to limit the current value of the power current. In fact, some components have a maximum current value limit. If the current flowing through the component exceeds the maximum current value, it will cause the component to burn. The power type adapter module 104 is a power current limiting module. Accordingly, the adaptation control signal is used to control the current value of the power current, so that the current value of the output power current is less than or equal to the current value of the current corresponding to the adaptation control signal, thereby protecting the image processor from burning. In fact, the power connector 101 and the image processing connector 103 only serve as a power supply channel and will not have any effect on the power current.

[0057] By configuring the power type adapter module as a power current limiting module, the current value of the power input to the image processor can be limited, protecting the image processor from burning out and improving power supply safety.

[0058] Optional, such as Figure 2As shown, the power type adaptation module 104 includes a current limiting protection device 105 and a current limiting control circuit 106; the current output end of the current limiting control circuit 106 is connected to the current limiting value control pin of the current limiting protection device 105; the input end of the current limiting control circuit 106 is connected to the signal connector; the power input end of the current limiting protection device 105 is connected to the power connector, and the power output end of the current limiting protection device 105 is connected to the image processing connector; the signal connector is used to send the adaptation control signal sent by the controller to the input end of the current limiting control circuit 106 to control the current value of the current output from the current limiting control circuit 106 to the current limiting value control pin, thereby controlling the current value of the power current output from the output end of the current limiting protection device 105.

[0059] The current limiting control circuit 106 is used to provide a limited current value. The current limiting control circuit 106 can control the output current value based on the input adaptation control signal. The input end of the current limiting control circuit 106 is connected to the signal connector for receiving the adaptation control signal. The output end of the current limiting control circuit 106 is connected to the current limiting protection device 105 for outputting a current corresponding to the adaptation control signal to the current limiting protection device 105.

[0060] The current limiting protection device 105 is used to limit the power supply current according to a limited current value. The current limit value control pin of the current limiting protection device 105 is connected to the output of the current limiting control circuit 106. The current limiting protection device 105 is used to receive the current corresponding to the adaptive control signal and limit the power supply current according to the current corresponding to the adaptive control signal, for example, controlling the power supply current value to be less than or equal to the current corresponding to the adaptive control signal. The output of the current limiting protection device 105 is connected to the image processing connector 103 and is used to output the limited power supply current to the image processing connector 103, so that the image processor receives the limited power supply current.

[0061] Exemplarily, the current limiting protection device 105 includes an e-fuse, and the specific model may be MP5022C. Among them, MP5022C is a hot-swap protection device used to protect the output circuit from the influence of input transients. MP5022C can also protect the input from output short circuit and transients. During startup, the inrush current is limited by setting the output voltage rise slope. The output voltage rise slope is controlled by an external capacitor connected to the SS pin. The maximum output load current is limited by a sampling FET (Field Effect Transistor) topology. The current limit value is set by a low-power resistor between ISET and ground. The gate of the power device is driven by an internal charge pump to control the conduction of the power FET with extremely low on-resistance (3mΩ).

[0062] For various types of power supply modules with different input voltages, the maximum current values ​​required by the GPU are not consistent.

[0063] In a specific example, for a 450W GPU powered by 12V, the maximum current is 450W / 12V = 37.5A; for a 600W GPU powered by 54V, the maximum current is 600W / 54V = 12A. A mechanism is designed to actively adjust the OCP (Over Current Protection) value for different current settings.

[0064] like Figure 3 As shown, the motherboard is equipped with a BMC (Baseboard Management Controller) management chip. In S5 state, the BMC first reads the FRU (Field Replacement Unit) information inside the power supply module (PSU) via I2C through signal connector 102. This FRU information can be used to determine whether the connected PSU is 12V or 54V. The current-limiting resistor value is then adjusted via the GPIO. The adaptive control signal can be a high-level signal or a low-level signal. When the GPIO sends a low level, Q1 is turned off, and the Iset (current limit setting) pin of the E-fuse is connected in series to ground through R1 and R2, setting the OCP to 40A for 12V power. When the GPIO sends a high level, Q1 is turned on, and the Iset (current limit setting) pin of the E-fuse is connected in parallel to ground through R1+R2 and R3, setting the OCP to 15A for 54V power. The BMC can also modify the OCP setting by adjusting the current-limiting register value via I2C.

[0065] By configuring the power type adaptation module as a current limiting protection device and a current limiting control circuit, the current limiting control circuit can output the corresponding current value according to the adaptation control signal determined by the type of the current supply module, and transmit it to the current limiting protection device, so that the current limiting protection device limits the power supply current according to the current value, ensuring that the current value input to the image processor will not burn the image processor, thereby improving the power supply safety of the image processor.

[0066] Optional, such as Figure 4 As shown, the image processing connector 103 is connected to an image processor, and the number of the image processing connector 103 is at least one, and the power connector 101 is connected to at least one power supply module.

[0067] There is at least one image processing connector 103, and accordingly, there is at least one image processor. The number of image processing connectors is the same as the number of image processors. There is at least one power connector 101, and accordingly, there is at least one power supply module. The number of image processing connectors is the same as the number of image processors. The power adapter board 100 enables multiple power supply modules to simultaneously power multiple image processors, greatly enhancing the expansion and power supply capabilities of the motherboard. This allows the motherboard to use multiple image processors, improving the image processing expansion capabilities. Among them, one power supply module can only power one image processor, or multiple power supply modules can power the same image processor. For example, multiple power supply modules can power multiple image processors. This can be determined based on image processing requirements or the types of image processors and power supply modules.

[0068] In a specific example, the front side (side A) of the power adapter board 100 connected to the 12V power supply module is as follows: Figure 5 As shown, the back side (B side) of the power adapter board 100 connected to the 12V power supply module is as shown in FIG. Figure 6As shown. The power connector 101 includes multiple power pins (A10-A18 or B10-B18) for connecting to the output ends of multiple power supply modules. The power connector 101 also includes multiple ground pins (A1-A9 or B1-B9) for grounding. There are 8 image processing connectors 103, which can power 8 GPUs at the same time. The signal connector 102 is connected to A19-A25 and B19-B25. A19-A25 and B19-B25 are respectively connected to the pins of each power supply module to transmit different signals so that the controller can monitor each power supply module. Among them, A1-A9 and B1-B9 have the same corresponding functions, and A10-A18 and B10-B18 have the same corresponding functions. In fact, the same pins are displayed on different sides of the power adapter board 100. The functions of A19-A25 and B19-B25 are different. On the front side (side A), A19 is connected to the data transmission pin (SDA) of the power supply module for data transmission, and A20 is connected to the clock transmission pin (SCL) of the power supply module for clock signal transmission. A21 is connected to the power supply module's on / off control pin (PS_ON) for controlling the start and stop of power supply. A22 is connected to the power supply module's warning pin (ALERT) for transmitting alarm signals. A23 (-Sense) and A24 (+Sense) are connected to the power supply module's sensors to collect information, such as voltage. A25 is connected to the power supply module's on / off output pin (PSOK) for outputting on / off control signals. On the back side (side B), B19 and B20 are connected to the address settings (ADDR0 and ADDR1) of the power supply module's registers for storing the starting and ending addresses. B21 is connected to the power supply module's shutdown / synchronization control pin (12V_SS) for synchronization. B22 is connected to the power supply module's safety lock pin (S_ON) to prevent the power supply module from being rewritten. B23 is connected to the power supply module's share pin (Share) for information sharing. B24 is connected to the power supply module's out-of-band signal pin (PRSNT) to support hot swapping. B25 is connected to the power supply module's power status pin (Vgood) to indicate whether the AC power (220V) input is normal.

[0069] For example, the front side (side A) of the power adapter board 100 connected to the 54V power supply module is as follows: Figure 7 As shown, the back side (B side) of the power adapter board 100 connected to the 54V power supply module is as shown in FIG. Figure 8As shown in the figure, compared to the power adapter board 100 connected to the 12V power supply module, the power adapter board 100 connected to the 54V power supply module lacks one power connection pin and one ground pin. Therefore, the 54V power supply module and the power adapter board 100 can be left unconnected. Compared to out-of-band signals, the 54V power supply module lacks the far-end and near-end voltage detection interfaces. Therefore, the voltage detection pins (A23 (-Sense) - A24 (+Sense)) on the 54V power supply module and the power adapter board 100 can be left unconnected. The voltage detection function can be implemented through the power supply module and the image processor's internal registers. The remaining power supplies and signals are identical.

[0070] The power adapter board 100 is connected to multiple power supply modules and multiple image processors, thereby improving the power supply capacity and enhancing the expansion capability of the mainboard.

[0071] Optionally, the power connector can be connected to a 12V power supply module or a 54V power supply module.

[0072] The 12V power supply module can power a 250W GPU or a 350W GPU, while the 54V power supply module can power a 450W GPU or a 600W GPU.

[0073] Existing motherboards can only support four PSUs. Based on a 2400W PSU and 2+2 redundancy, the entire system can only support a maximum power consumption of 4800W. After deducting the power consumption of the CPU, fans, and other power supplies, this is insufficient to power eight 450W GPUs. Furthermore, because the PSU is directly connected to the motherboard, the PSU output voltage is essentially limited to 12V, not 54V, which limits the power consumption of a single PSU.

[0074] In a specific example, Figure 5-Figure 6 The power connector 101 in the circuit adapter board 100 shown is configured with 8 pins, which can connect to a maximum of 8 PSUs at the same time. In addition, the image processing connector 103 is configured with a maximum of 8 pins, which can connect to a maximum of 8 GPUs at the same time.

[0075] In addition, after the BMC identifies the power type through I2C in advance, it can also perform different voltage detection, overvoltage protection and undervoltage protection for 12V and 54V power supplies.

[0076] A 12V power supply module or a 54V power supply module can be connected through the power adapter board 100, which can achieve compatibility with low-power and high-power GPU power supply. It can even meet the power supply needs of future higher-power GPUs, break through the power consumption limitations, increase the power supply expansion capability, and thus increase the expansion capability of image processing.

[0077] Optional, such as Figure 9The power adapter board 100 shown also includes: a first capacitor 107 and a second capacitor 108; the first end of the first capacitor 107 is connected to the power connector 101; the first end of the second capacitor 108 is connected to the image processing connector 103; the second end of the first capacitor 107 and the second end of the second capacitor 108 are grounded.

[0078] The schematic diagram of the circuit on the power adapter board 100 is as follows: Figure 10 The first capacitor and the second capacitor are used to filter the power supply current, and the number of the first capacitor and the number of the second capacitor are at least one.

[0079] Wherein, the capacitance value of the first capacitor and the capacitance value of the second capacitor are adapted to the type of the power supply module. Exemplarily, for the selection of filter capacitors, in order to consider the compatibility of 12V and 54V, high-voltage capacitors are uniformly selected. Or a BOM (Bill Of Material) option is selected, that is, the same capacitor package (footprint) is designed on the circuit adapter board 100. When using a 12V PSU, a capacitor with a voltage resistance of 16V or 25V is installed. When using a 54V PSU, a capacitor with a voltage resistance of 63V is installed to achieve the purpose of reducing costs. Or a capacitor with a voltage resistance of 63V is installed, which can be compatible with 12V PSU and 54V PSU.

[0080] By setting capacitors in the power adapter board, the power supply current can be filtered, the AC ripple coefficient can be reduced, and the efficient and smooth DC output can be improved.

[0081] Optionally, an electronic device 500 includes: a power adapter board 100, a power supply module 200, an image processor 300 and a main board 400 as in any embodiment of the present disclosure; the power adapter board 100 is respectively connected to the power supply module 200, the image processor 300 and the main board 400; wherein a controller 401 is provided on the main board 400; the power adapter board 100 is connected to the controller 401 on the main board 400 by connecting to the main board 400.

[0082] The number of the power supply module 200 and the number of the image processor 300 are both at least one, and the numbers can be different or the same.

[0083] According to the technical solution disclosed in the present invention, an independent power adapter board is used to power the GPU, which can not only meet the power supply requirements of high-power GPUs, but also be independent of the motherboard to achieve power decoupling. In addition, the power adapter board does not need to support high-speed signals and can use low-grade PCB materials. The cost of the power adapter board can be recovered from the cost savings of the motherboard. Compared with the existing solution, the number of PSUs is increased from 4 to 6, which is a necessary requirement to support future high-power GPUs. In addition, electronic devices can directly use existing general motherboards without the need for new designs. Currently, it can support 12V and 54V high-power GPUs and is compatible with the latest 450w12V and next-generation 600w 54V GPU products. It can be compatible with different types of power supplies, improving the compatibility of the power adapter board, and can provide adaptive power current for GPUs with different power consumption requirements, improving the expansion capabilities of the motherboard.

[0084] Optionally, the electronic device 500 includes a server.

[0085] The electronic device 500 is a server. Configuring an independent power adapter board in the server can greatly increase the image processing expansion capability and improve image processing performance. The server can be a GPU server.

[0086] By configuring electronic devices as servers, the routing and device layout on the motherboard can be optimized, the server space can be optimized, and the power supply limitations of the motherboard can be broken through, thereby improving the expansion capabilities of the motherboard, improving the expansion capabilities of the server, and improving the overall power supply efficiency of the server.

[0087] Figure 12 This is a schematic diagram of a power supply method according to an embodiment of the present disclosure. This embodiment can be applied to providing power to multiple image processors. This method can be performed by an electronic device as described in any of the embodiments of the present disclosure. This electronic device can be implemented using software and / or hardware and has certain data processing capabilities. This electronic device can be a server.

[0088] S101: A controller on the mainboard obtains type information of a power supply module through a circuit adapter board.

[0089] The controller on the mainboard reads the FRU information from the power supply module through the signal connector on the circuit adapter board and determines the type of the power supply module. The mainboard memory may pre-store a correspondence between the FRU information and the type information. The controller reads the FRU information and determines the type of the power supply module based on the pre-stored correspondence.

[0090] S102: The controller generates an adaptation control signal according to the type information and sends the adaptation control signal to the power adapter board.

[0091] The controller generates adaptation control information based on the type information, generates a high-level signal or a low-level signal based on the type information, sends it to the current limiting control circuit of the power type adapter module in the power adapter board, generates the corresponding current value, and transmits it to the current limiting protection device of the power type adapter module.

[0092] S103, the controller controls the power supply module to output power current through the circuit adapter board.

[0093] The controller sends a power supply start signal to the power supply module through the power switch pin on the circuit adapter board, controlling the power supply module to start outputting power current. It can also send a power supply stop signal to control the power supply module to stop outputting power current.

[0094] S104 , the power adapter board converts the power current output by the power supply module into a power current corresponding to the adaptation control signal according to the adaptation control signal, and outputs the converted power current to the image processor.

[0095] The power adapter receives the power current output from the power supply module via the power connector. Based on the current value corresponding to the adaptation control signal, the power adapter limits the maximum current and transmits the limited current to the image processing connector within the power adapter, which then forwards it to the image processor.

[0096] In the existing technology, the motherboard provides power for the connected GPU. The power supply that the motherboard can support is limited, and the pin space that can be laid out is also limited, resulting in limited power consumption. The GPU and motherboard share a power supply. Once the GPU malfunctions, it will affect the motherboard production line, which may cause abnormal power outages or even damage to the motherboard, resulting in poor system stability. The existing general motherboard design only supports 2 PSUs, and the design power consumption is within 4000w, which is not enough to support an 8-GPU configuration. If support for 8 GPUs is required, the motherboard can only be designed from the ground up to support more PSUs. Therefore, a large amount of manpower and material costs need to be invested in the design and verification of the new motherboard, and a new motherboard design is required.

[0097] According to the technical solution disclosed in the present invention, an independent power adapter board is used to power the GPU, which can not only meet the power supply requirements of high-power GPUs, but also be independent of the motherboard, realize power decoupling, expand power consumption, reduce the space occupied by the motherboard, adapt to GPUs with higher power consumption, and do not need to modify the motherboard, thereby reducing the implementation cost and development cost of power supply, and avoiding the GPU and motherboard from sharing power supply, thereby improving the stability of the power supply system. Through the power type adapter module on the power adapter board, it can be compatible with different types of power supplies, thereby improving the compatibility of the power adapter board, and can provide adaptive power current for GPUs with different power consumption requirements, thereby improving the expansion capability of the motherboard.

[0098] Optionally, the power supply method further includes: the controller obtains the power supply voltage of the power supply module through the circuit adapter board; the controller obtains the voltage detection threshold corresponding to the type information; and the controller detects the safety of the power supply voltage based on the voltage detection threshold.

[0099] The circuit adapter board can detect the voltage of the power supply module through a voltage sensor, for example, reading the voltage as in the previous example A23 and A24, or directly obtain the voltage of the power supply module from a register of the power supply module.

[0100] The voltage detection threshold is used to check whether the power supply module is properly supplying power. Based on the voltage detection threshold, the controller detects safety issues with the power supply module's voltage and issues an alarm. Different power supply modules provide different power voltages, requiring corresponding voltage detection thresholds for different power supply voltages. For example, the voltage detection threshold for a 12V power supply module is 10V, while the voltage detection threshold for a 54V power supply module is 56V.

[0101] For example, if the power supply voltage is greater than the voltage detection threshold, a safety issue may be determined and an alarm may be issued. For another example, if the power supply voltage is less than the voltage detection threshold, a safety issue may be determined and an alarm may be issued.

[0102] In addition to alarms, you can also configure corresponding handling strategies. For example, you can reduce GPU frequency and fan speed to ensure normal server operation even without a PSU, thereby protecting the server from power outages. This reduces the number of PSUs required for the server itself, ensuring server service security in the event of power outages without increasing the cost of redundant power supplies. Other methods are also available and can be configured as needed, but are not specifically limited to these.

[0103] By determining the corresponding voltage detection threshold for different types of power supply voltages, the power supply module is tested for safety, and overvoltage and undervoltage protection are implemented for the circuits in the circuit adapter board, thereby improving the power supply safety of the circuit adapter board.

[0104] In the technical solutions disclosed herein, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved comply with the provisions of relevant laws and regulations and do not violate public order and good morals.
